Rejection of arsenic minerals in sulfide flotation — A

Oct 01, 2009· The oxidation rate of arsenic minerals and non-arsenic minerals has been compared in a series of papers to explain the selective flotation of arsenic minerals from other sulfide minerals. According to Iwasaki et al. (1988), nickel arsenide (Ni 11 As 8) is much more easily oxidized than pyrrhotite, pentlandite, chalcopyrite and cubanite.

Arsenide depression in flotation of multi-sulfide minerals

The present invention relates generally to the field of mineral separation and in particular to a flotation process for depressing arsenic minerals using the synergistic combination of a polyamine, a sulfur containing species, and oxidation. The production of most metals proceeds in two steps.

Arsenic Mining Processing Equipment Flow Chart Cases

Arsenic metal very rarely occurs in its pure form in nature. The most common arsenic mineral is arsenopyrite, a compound of iron, arsenic, and sulfur. Several other, less-common minerals contain arsenic, including orpiment, realgar, and enargite, which are arsenic sulfides.

THE USE OF PULP POTENTIAL CONTROL TO SEPARATE

In copper deposits, arsenic is often present in the form of the copper-arsenic minerals, enargite (Cu. 3. AsS. 4) and tennantite (Cu. 12. As. 4. S. 13). Under normal circumstances, the flotation response of these minerals is generally similar to that of the common copper sulfide and copper-iron sulfide minerals using flotation conditions

2. How To Remove Arsenic In Gold Ore By Gold Flotation Separation? Arsenic not only has a great impact on the quality of gold concentrate ore, but also pollutes the environment. Arsenic in gold ore is generally found in arsenopyrite, the gangue mineral, and it is more closely disseminated with gold minerals and is more difficult to separate.

Break Through Carlin-type Gold Mineral Processing

For the beneficiation of arsenic-containing gold ore, it is first necessary to perform aeration before flotation to promote ore oxidation to remove arsenic minerals on the surface of arsenopyrite. Meanwhile, a strong collector reagent, such as BK903G, BK302A or MA, is used to improve the flotation effect of fine-grained gold and gold carrier
